doctrine/common — pull request #342 by Ocramius (2014-11-11 14:54:13+00:00)
Title: Class metadata loading fallback hook

Enables loading class metadata when loading failed (in subclasses).

See doctrine/doctrine2#385

Note that I preferred inheritance to avoid having an `EventManager` in here, though it may be a perfectly acceptable dependency in this case, therefore it is up for discussion.
